The Q Smart Ring 3 Pro is a titanium-style smart ring that tracks sleep stages, heart rate, HRV, SpO2, skin temperature, stress, steps, calories and workouts, with a touchable surface that shows calls and SMS. It comes with a 200mAh charging case that Q says stretches use to about 30 days, and there are no subscription fees. At roughly 3.3g it is light enough to forget, and buyers say readings for heart rate, blood oxygen and sleep hold up against other devices. It suits people who want overnight and all-day tracking without a watch, though it is bulkier than some rings and one owner found the heart rate read high.

Buyers rate the Q Smart Ring 3 Pro well for accuracy, comfort and battery life. They like the easy setup, the free app and the absence of a subscription. Complaints are few: one heart rate reading ran high, and some find it bulky.
